Heading east from Thief Lake WMA I decided to check out Norris Camp, a remote Minnesota DNR station in the Beltrami Island State Forest that I’d heard had a nesting Black-backed Woodpecker. I was pretty sure that I was too late as most woodpeckers had fledged young already. But I was in luck! And I spent a couple hours with this pair of rarely seen boreal woodpeckers.

The folks at the camp pointed out that this was the same mated pair that nested on the grounds last summer. How did they know? Notice the band on the adult’s leg; they actually banded them last year and both the male and female returned to nest only 100 yards from last year’s nest. Woodpeckers NEVER use the same cavity twice but always excavate a new nest; it may be in the same tree but usually not. In this case, the tree they used last year had blown down since last summer. I don’t know much about site fidelity or mate fidelity in woodpeckers but this was a very interesting anecdote that I will for follow up on.
Also note the male’s yellow cap; the female shows only black on the head. He’s feeding a young male who is already sporting his jaunty yellow forehead feathers.

Macoun’s Arctic (Oenis macounii) at Norris Camp, Beltrami Island State Forest, Lake of the Woods County, Minnesota.
While waiting and watching at the Black-backed Woodpecker nest, I was treated to a lifer butterfly. Not 20 feet away I noticed an orange butterfly that was repeatedly landing on the same fallen log. I finally took a closer look and lo and behold, a Macoun’s Arctic! This species only flies every other year in the North Woods so I just happened to be in the right place at the right time. They are found in openings in sandy Jack Pine forests, and that is exactly the habitat I was in. Males use the same perch as they wait for females.

Macoun’s Arctic (Oenis macounii) at Norris Camp, Beltrami Island State Forest, Lake of the Woods County, Minnesota.
When perched with wings folded, the Macoun’s Arctic is well camouflaged, like just another piece of bark. This species has a fairly limited range in North America extending from the North Shore of Lake Superior west and north to Churchill, Manitoba, British Columbia and just extending north into the Northwest Territories.

Ram’s-head Ladyslipper (Cypripedium arietinum) near Norris Camp in Beltrami Island State Forest, Lake of the Woods County, Minnesota.
One of my favorite orchids found in the bogs of north central Minnesota, the Ram’s-head Ladyslipper. This small group was past prime as you can tell by the collapsed dorsal sepal on top of the slipper pouch. This may mean that the flower had already been pollinated. It is a very small ladyslipper, maybe 6 inches tall. This group was growing in a Cedar bog.

My last stop was Big Bog State Recreation Area (SRA) near Waskish, Minnesota on Red Lake. This is the largest patterned peatland in the lower 48, and massive in size. It was once home to Minnesota’s last wild Caribou herd which disappeared in the 1930s and 40s. Their trails can still be seen from the air.
The boardwalks is one mile long and a very pleasant hike. MANY interpretive signs highlight the human and natural history of the Big Bog.

Bog Fritillary (Boloria eunomia) on the Big Bog SRA boardwalk.
This was my lifer Bog Fritillary! Unfortunately I mistook it for a different, more common species, and I didn’t take the time to get a really good photo. Oh well, just a reason to go back!
I was going to camp overnight in the area, but I got a text message on my phone that a Calliope Hummingbird had shown up in Duluth…in breeding plumage! This is a bird of the mountain west that has only been recorded in Minnesota a couple times…and never in its stunning breeding plumage. This was reason enough to head for home.

My road trip in late June led me from Wrenshall, Minnesota to a place I’d long wanted to visit. It is called Oak Hammock Marsh and it is about 30 minutes north of Winnipeg, Manitoba. This is how their website describes it…”Oak Hammock Marsh is one of North America’s birding hotspots and a great destination for people of all ages. This 36km2 Wildlife Management Area features a restored prairie marsh, aspen-oak bluff, waterfowl lure crops, artesian springs, some of Manitoba’s last remaining patches of tall-grass prairie and 30 kilometers of trails for you to explore. …the Interpretive Centre features wheelchair-accessible facilities including a 120-seat multimedia theatre, a scenic café, a gift shop, meeting rooms, rooftop observation deck, and interactive exhibits.” Visit their website for a bird list and more info.

Can you spot the Killdeer eggs? Yes, this is all the “nest” they need…just a scrape in the dirt of a parking pad. They prefer spots with much rocks-gravel in order to provide camouflage to their splotched eggs.

Mom Killdeer is sitting tight to her nest as I crawl closer and closer. She eventually pops off the nest and tries to lure the vicious predator (me) away from her nest with a “broken-wing” display. I didn’t want to stress her unduly so I moved on. [Canon 7D with Canon 400mm f5.6 lens, 1/250 at f8; ISO 100; pop-up flash -2 2/3ev; hand-held while crawling on my belly]

It was good to see a very active Purple Martin nest box near the edge of the marsh. It is an all too rare sight in Minnesota these days. Purple Martins are actually giant swallows who feast on aerial insects, often near water.

Yellow-headed Blackbirds are rare in northeastern Minnesota, so it is a treat to see them and hear their raspy “song.” They actually outcompete Red-winged Blackbirds and claim the safer nest sites deep in the cattails forcing Red-wings to nest at the margins of the marsh.

Marsh Wrens are very well named as they nest smack dab in the middle of dense stands of marsh cattails. Their “sewing machine” song (sounds like an old treadle sewing machine) rattles from many territorial birds along the walkways.

Black Tern’s wings are paler than their jet black body. You really need at least 1/1600 of a second shutter speed to freeze the motion of the wings of terns and gulls in flight. [Canon 7D with Canon 400mm f5.6 lens, 1/1600 at f6.3; ISO 200; hand-held]

Black Tern

Black Terns are quite rare in northeastern Minnesota, so it was a real treat to see this large colony. They don’t dive and plunge into the water like many of the “white terns” but rather delicately pluck aquatic critters and tiny fish off the surface.

White Water Crowfoot (Ranunculus aquatilis) grows in the sluggish backwaters of the marsh.

Not a great photo…But my best photo ever of a Nelson’s “Sharp-tailed” Sparrow. This shy cattail-lover is rarely seen in migration and nests in sedge and cattail marshes from north-central Minnesota (McGregor Marsh) up to northern Saskatchewan. Other populations nest along saltwater in NE North America and along Hudson’s Bay. Their subtle song has been described as someone dousing a hot poker in a vat of oil…and that’s about right. This guy appeared at dusk. The “tick-ticking” of a Yellow Rail joined several singing LeConte’s Sparrows as a big thunderhead rolled on south of me.

LeConte’s Sparrows were “dirt common” in the northwest portion of Oak Hammock. They are fairly common in my home ground of the Sax-Zim Bog but this was amazing! Every wet meadow seemed to hold several. Photo taken at dusk. This is a fairly “noisy” photo because it was shot at ISO 2000(!) but it nicely shows the habitat and orangey color of this not-oft-seen bird.

I found this canid skull in the marsh. I love finding skulls as it is really the ultimate track of an animal.

This impressive multi-million dollar building is also the Headquarters of Ducks Unlimited Canada. The marsh buts right up to the walls and you can watch Black Terns and ducks right from the windows.

The mission of the Oak Hammock Marsh Interpretive Centre is to connect people with wetlands and they do it via outdoor activities and indoor displays and classes.
